Not very efficient solution -- it'll update mapping node on init ntree exec and will not work for viewport GLSL shading perhaps, but it's as good as it could be within current dependency graph. The issue here is that manual edit of values will cause cached matrix re-evaluation. but using animation does not use rna update callbacks hence no matrix update was happening.
